The issue can be fixed by updating file doctrine-dbal.php from:$classLoader = new \Doctrine\Common\ClassLoader('Symfony', 'Doctrine');
to:$classLoader = new \Doctrine\Common\ClassLoader('Symfony');
so the Symfony Console package can be used like the PEAR package.xml requires.

NOTE: I did not want to submit a GitHub pull request for this because it seems like it would break your Git and Composer installs
